钻杆的失效分析和检测现状及其研究进展

Research Progress and Detection Current Status and Progress of Drill Pipe Failure

介绍了钻杆的使用现状及钻杆失效分析研究进展,表明腐蚀疲劳及管体刺穿是钻杆失效的主要原因及失效形式。概述了目前钻杆无损检测的应用情况,超声波探伤目前应用最为广泛,但是单一检测手段越来越难以满足检测要求,多手段综合检测是未来钻杆无损检测的发展方向。

The drill pipe failure analysis research progress was introduced.The corrosion fatigue and tube pierced the drill pipe are the main reasons for the failure and failure modes.A brief overview of the application of non-destructive testing of drill pipe,indicating a single mean of detection is difficult to meet the testing requirements.Various means testing is the future direction of the development of non-destructive testing drill pipe.
